Development of an Internal Combustion Engine for Shell Eco-marathon Competition Vehicle

  • 1 TTK University of Applied Sciences, Estonia

Abstract

In this article, the authors describe the development process of a custom internal combustion engine (ICE) for a vehicle competing in the Shell Eco-marathon. The engine will be designed to replace the Honda GX35 previously used in the vehicle. The new engine has to comply with competition regulations and improve the overall fuel efficiency of the vehicle. An engine test stand was developed for measuring the power and brake-specific fuel consumption (BSFC) of small IC engines which allowed tests to be carried out on the GX35 to collect data for the design. Based on the data obtained from the tests and the information gathered from educational materials, a suitable IC engine will be later developed.
